VENTILATOR.

Specification of Letters Patent.

Patented Aug. 1U, 1920.

Application filed 'March 8, 1920. Serial No. 364,171.

To all whom t may concern Be it known that I, LnoNonA CHAPMAN, a citizen of the United States, residing at Ariel, in the county of IVayne and State of Pennsylvania, have invented certain new and useful Improvements in Ventilators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in ventilation, and it has more particular reference to ventilators for windows. y

The object of the invention is to generally improve upon the construction of such devices, especially as to the means en1- ployed for retaining the device in position in the window, this means being such that it will permit the shield or body member to be arranged at various positions to admit more or less air, as the case may be. Not only dees this novel retaining-means permit the shield to be moved to a position to admit more or less air, but it permits it to be adjusted so as to permit the passage of air be- In this way the air may be directed along the floor if desired, or the shield may be angled to admit air between its bottom edge and the sill, and over its top edge at the same time.

Another object of the invention is to provide a window ventilator which is adjustable to tit various widths of windows; one which is simple and eective, strong, durable, easy to install and inexpensive to both the manufacturer and the user.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same:

Figure l is an elevation of a ventilator constructed in accordance with my invention, the same being shown in position in the window, the view being taken from the interior of a room.

Fig. 2 is a longitudinal sectional view taken on the plane of the line 2-2 of Fig. 3 is a transverse vertical section on the line 3 3 of Fig. 1.

In carrying out my invention I employ a body member composed of slidably connected sections, each of which includes a laterally extending end wall for disposition against the window frame. Said member is prevented from falling out of the window by a novel brace which is composed of extensible members which coact with end walls and are held in adjusted position by any suitable means.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral l designates a window frame in which my improved ventilator is positioned. The latter is in the form of a segmental drum which includes a pair of slidably connected arcuate sections 2 which because of this construction, may be installed in windows of various widths. Each section, carries a laterally disposed, apertured end wall 3 which is adapted for disposition against the frame l in the manner illustrated.

To hold said members 2 in position in the window, I employ an extensible brace or retaining member 4. .The latter is made up of two arms or bars 5, each of which has one of its ends bent laterally as at 6 for connection to the end walls However, they need not be connected, because the desired result may be accomplished without such connection, whichis merely used to keep the parts together so that when the sections 2 are adjusted the bars 5 will also be adjusted. TIhen again, by securing the bars in this manner, the parts will always stay together and will not become lost, so, it will be seen, that this construction is preferable but is not essential. It is to be noted thatl when in use, the lateral ends of the bars extend across the apertures in the end walls so that the threaded-openings therein will register with the apertures and permit the insertion of headed binding screws 7 through them, the heads of the screws being permitted to engage the frame. The free ends of the bars 5 are lapped, one on the other and are held together by a collar 8 which permits them to slide freely through it. Collar 8 carries a set screw 9 which, as is obvious, serves to lock the bars against sliding movement when the device is 1n the window. However, while I have shown a collar and set screw for this purpose I desire it to be understood that any other suitable means may be employed for the purpose of retaining the bars in adjusted pon sition.

In use, the sections 2 will be adjusted to fit the particular window in which they are to be positioned, this being accomplished by moving the end walls 3 toward or from each other, as the case may be. Such movement of 'the members will `automatically adjust the bars 5, whereupon the set screw 9 may be tightened to hold the parts in adjust- 'ed position, Under ordinary circumstances vsuch operation will retain the Vdevice in the i portant purpose,that is, they permit the sec- `tions 2 'tol be angled so that air may be admitted between the bottom edges thereof and the window sill. This feature may be accomplished by merely loosening the screws 7. In this Way the incoming air will be directed toward and along the floor of the room as is oftentimes desirable. In no circumstances, however, will a direct draft be permitted.

A device constructed in accordance with my invention will be found extremelyuseful because it is easy to install, effective in use, and inexpensive. It will absolutely prevent the creation of direct drafts and vwill permit the entrance of air between itself and the window sill. VIt is adjustable to fit various widths of windows and adjustment of the shield sections will automatically adjust the retaining members which is advantageous as it is obvious.

By carefully considering the foregoing description inY connection with the accompanying drawings, the reader will be able to obtain a thorough idea of the construc- Ytion of the device and the manner in which it is used. In view of this I do not deem it i necessary to furtherl describe the saine;

neaaiseV It is to be understood that the form of the invention herein shown and described is to betaken 'as a preferred form of the saine, and that minor changes in the shape, size, and-arrangement of parts may be resortedto without departing from the spirit of the invention or the scope of the subjoined claims. i

I claim: n

l. A window ventilator comprising a body member composed of adjustably connected sections, each' including a laterally extending,'apertured end wallfor disposition against the frame of a window, two relatively movable bars having laterally'directed ends` secured to the end walls, these lateral ends being `provided with screwthreaded openings registering with the apertures inl the end walls, binding screws eX- tending through said screw-threaded openings, apertures, and being adapted to bear Vagainst the window frame, and means'to retain the bars in adjusted position.

2. A window ventilator comprising a lengthwise adjustable segmental drum composed of slidably connected arcuate sections, each section including a laterally extending, apertured end wall for disposition against the window frame, two vbars having laterally bent ends which are secured to the end walls and are provided with screw-threaded openings registering with the apertures in the end walls, headed binding screws eX- tending through the threaded openings and apertures, the heads thereof being adapted to bear against the window frame, the free ends of saidbars being lapped one on the other, a collar surrounding the lapped ends, and a set screw carried by the collar for retaining the bars in adjusted position.

In testimony whereof I have hereunto set my hand.
